Subject: Final NPDES Permit Renewal & Expansion
Permit NC0027103
Pembroke WWTP
Robeson County
Grade III Biological WPCS
SIC Code 4952
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007
(or as subsequently amended).
No changes were made to the draft sent to you on June 6, 2022; this final permit maintains
the following significant changes identified in the letter sent on June 6, 2022:
• Based on the Town's request to modify the permit to authorize a plant expansion to 2.0 MGD,
review and approval of the submitted Engineering Report/Environmental Information
Document for the proposed expansion, an Effluent Limits and Monitoring Requirements sheet
for 2.0 MGD has been added to the permit [See A. (2.)].
• A component list for the proposed 2.0 MGD expansion flow tier has been added to the
Supplement to Permit Cover Sheet.
• As part of the expansion review, updated streamflows at the discharge were calculated by
USGS at Division request. The resulting updated streamflows were used in updating a set of
speculative limits that were originally calculated for the 2.0 expansion flow in 2013. As a
result, the whole effluent toxicity test limit has been revised from 1.7% effluent to 3.0%
effluent at 1.33 MGD [See A. (1.)] and a 4.5% limit was added at 2.0 MGD [See A. (2.)].
• The Town reported Total Silver at less than detection, with detection levels < 5.0 µg/L, and <
3.0 µg/L in the submitted Effluent Pollutant Scan results. The Town's allowable discharge
concentrations for Total Silver are 1.0 µg/L at 1.33 MGD and 0.7 µg/L at 2.0 MGD. DWR's
laboratory identifies the target Practical Quantification Limits (PQLs) for silver is 1.0 µg/L.

7. The Permittee shall perform three Effluent Pollutant Scans and four second -species effluent toxicity tests during the term
of this permit. See Special Condition A. (4.).
1. There shall be no discharge of floating solids or visible foam in other than trace amounts.
A.(3.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly) [15A NCAC 02B.0200 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 3.0% at 1.33 MGD and 4.5% at 2.0
MGD.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised December 2010) or subsequent versions. The tests will be performed during the months of
January, April, July, and October. These months signify the first month of each three-month toxicity
testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during
representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge
below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or Chronic
Value (ChV) below the permit limit, then multiple -concentration testing shall be performed at a
minimum, in each of the two following months as described in "North Carolina Phase II Chronic
Whole Effluent Toxicity Test Procedure" (Revised -December 2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered electronically using the
Division's eDMR system for the months in which tests were performed, using the parameter code TGP3B
for the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT-3 (original) is
to be sent to the following address:

Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that Municipal
facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to
additional toxicity testing requirements specified in Federal Regulation 40 CFR 122.21(j)(5). The US EPA
requires four (4) toxicity tests for a test organism other than the test species currently required in this
permit. The second species tests should be conducted either quarterly for a 12-month period prior to
submittal of the permit renewal application, or four tests performed at least annually in the four and one-
half year (41/2) period prior to the application. Samples should be collected with one quarterly toxicity test
each year, and must represent seasonal variation [i.e., do not sample in the same quarter every year].
These tests shall be performed for acute or chronic toxicity, whichever is specified in this permit. The
multiple species toxicity test results shall be filed with the Aquatic Toxicology Branch at the following
address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Or results can be sent to the email: [e-mail].
Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the
additional toxicity tests and reporting requirements. Results should also be summarized in Part E (Toxicity
Testing Data) of EPA Municipal Application Form 2A, when submitting the permit renewal application
to the NPDES Permitting Unit.

A.(5.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[NCGS 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program
reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December 21,
2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted monthly electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit monthly DMRs electronically using the internet. The eDMR system may
be accessed at: https://deq.nc.gov/about/divisions/water-resources/edmr.
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or alternative
forms approved by the Director. Duplicate signed copies shall be submitted to the following address:
NC Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
See "How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following the
issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2025, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act (CWA) Section 316(b) Annual Reports.
Page 11 of 14

DocuSign Envelope ID:201D1003-DBC7-4999-BB35-66C07A5B4E80
Permit No. NC0027103
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of
each electronic submission. The permittee should use the EPA's website resources to identify the
initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity
for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each
type of electronic submission and for each state. Instructions on how to access and use the appropriate
electronic reporting tool will be available as well. Information on EPA's NPDES Electronic Reporting
Rule is found at:
https://www.federalregister.gov/documents/2015/ 10/22/2015-24954/national-pollutant-discharge-
elimination-system-npdes-electronic-reporting-rule
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The Permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the
Division. Requests for temporary electronic reporting waivers must be submitted in writing to the
Division for written approval at least sixty (60) days prior to the date the facility would be required
under this permit to begin submitting monitoring data and reports. The duration of a temporary waiver
shall not exceed five (5) years and shall thereupon expire. At such time, monitoring data and reports
shall be submitted electronically to the Division unless the Permittee re -applies for and is granted a
new temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are
not transferrable. Only permittees with an approved reporting waiver request may submit monitoring
data and reports on paper to the Division for the period that the approved reporting waiver request is
effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
http://deq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II,
Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II, Section
B. (11.)(b). A person, and not a position, must be delegated signatory authority for eDMR reporting
purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North Carolina's
